Load may refer to any of the following:
1. Load refers to the beginning or executing a program by moving (loading) the necessary information from a drive, such as a hard drive, into a computer's memory. Depending how much information is required to load, the speed of the hardware, and how other programs are running determines the load time. If a program or command gives you a load average, the average is on average how long it takes to load or execute a process.
2. When referring to electronics, a load is any circuit or device opposing electrical current.
